Oh give it up. Jesus called Peter Cephas which is Aramaic the language that Jesus spoke and means rock. In Greek the word is Petros and in English it is Peter. Wow! Wasnt that neat? So what? It still doesnt mean that the church is built upon Peter as the foundation.

Paul made it rather clear.

1 Cor. 3:11 For other foundation no one can lay, but that which has been laid, which is Christ Jesus

I shouldnt have said the Father. God, and these three are one, the Rock upon which the church is built.

Neither is the Pope the head of the church.

Eph. 5:23-24 "Let wives be subject to their husbands as to the Lord; because a husband is the head of the wife, just as Christ is head of the Church, being himself savior of the body. But just as the Church is subject to Christ, so also let the wives be to their husbands in all things."
